HUB=ATTACHING DEVICE.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed November 1,1904. SeriaINo. 230,985-

To all whom, it nan/y coil/carna- Be it known that I, ALFRED HARVEY IVOR- REST, a resident of Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improve ments in Hub-Attaching Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved hubattaching device, the object of the invention being to provide an improved construction of butt-ring and improved mechanism acting as a nut-lock to firmly secure the same at any adjustment; and the invention consistsin certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view showing the axle in elevation and the box, butt-ring, and locking device in section. Fig. 2 is aview of the butt-ring removed, and

3 is a view of the locking-ring.

1 represents an axle provided withaball or spherical enlargement 2, and 3 is the hub-box, fitting the axle and mounted to turn thereon. The inner end of the box 3 is enlarged to receive ball 9. and lit one side or half thereof, and the enlarged end portion A of the box which extends out beyond ball 2 is internally screw-threaded to receive external screwthreads on my improved butt-ring 5. Buttring 5 is made in two half-sections hinged together to enable its being readily placed around axle 1 or removed therefrom, and an annular shoulder or enlargement 6 is provided around the rear end of ring 5, and the inner end of box 3 is made with an annular recess or pocket 7 to receive and house a nutlocking ring 8, which will be more fully hereinafterdescribed. The inner end of butt-ring 5 is shaped to lit against the ball 2 on axle 1 and can be adjusted to take up wear and insure a perfect running-box on the axle, and the locking-ring 8 is to effectually secure this butt-ring 5 at any adjustment and against possibility of accidental movement.

The locking-ring 8 shown consists of a spring-wire having corrugations or scalloped in circular arrangement to form a series of spring bearing faces or points, bearing against the wall of recess or pocket 7 and the annular shoulder 6 of ring 5 and capable of compression to bind the screw-threads of buttring 5 against those of box 3 and effectually lock the butt-ring at any adjustment.

\Vhile I describe and illustrate a lockingring 8 of a particular form, I Wish it dis tinctly understood that I do not restrict myself thereto, but wish to cover any compressible device or devices of any material and form which may be inserted between the butt-ring shoulder and box recess and act to bind the ring and prevent its accidental displacement. In other words, I wish to cover broadly any locking means for this butt-ring, whether such means be located between the butt-ring and box or back of the ring, and do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with an axle having a spherical enlargement, of an axle-box enlarged at one end and having a bearing against said spherical enlargement, a butt-ring screwed into the enlarged end of the box and bearing against said spherical enlargement, an annular flange projecting from the rear end of said box and forming a chamber around the buttring, a shoulder on the butt-ring closing said chamber, and a spring located in said chamber, and bearing against said shoulder and box.

2. The combination with an axle having a spherical enlargement and an axle-box having a bearing against said spherical enlargement, of a divided butt-ring comprising two sections hinged together and screwed into the axlebox, said ring having a bearing against the spherical enlargement on the axle, and a spring interposedbetween the butt-ring and axlebox and tending to press these parts in opposite directions.

3. The combination with an axle having a spherical enlargement, and an axle-box having a bearing against said enlargement, said box having an annular flange at its rear end forming an annular chamber, of a butt-ring screwed into said box and. forming the inner Wall of specification in the presence of two subscribsaid annular chamber, ashoulder on the butt- I ing Witnesses. ring closing said annular chamber, and aeor- ALFRED HARVFY VVORPFST rugated spring-ring inclosed Within said an- I J J 5 nulal' chamber and bearing against the shoulder on the butt-ringand against the axle-box. In testimony whereof I have signed this I Vitnesses:
